Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31588926, here are decompositions:

29 + 31588897 = 31588926
79 + 31588847 = 31588926
113 + 31588813 = 31588926
227 + 31588699 = 31588926
233 + 31588693 = 31588926
269 + 31588657 = 31588926
283 + 31588643 = 31588926
433 + 31588493 = 31588926

Showing the first eight; more decompositions exist.
